Tyrosinase family related genes plays an important role in the evolution, genetics, and developmental biology of pigment cells, as well as to approach human disorders associated with defects in their synthesis, regulation or function in vertebrates three types of melanin producing pigment cells are well known since embryonic origin i.e., from ...
A tyrosine kinase is an enzyme that can transfer a phosphate group from ATP to the tyrosine residues of specific proteins inside a cell. It functions as an "on" or "off" switch in many cellular functions.
L-Tyrosine or tyrosine (symbol Tyr or Y) [2] or 4-hydroxyphenylalanine is one of the 20 standard amino acids that are used by cells to synthesize proteins.It is a conditionally essential amino acid with a polar side group.
Receptor tyrosine kinases (RTKs) are the high-affinity cell surface receptors for many polypeptide growth factors, cytokines, and hormones.Of the 90 unique tyrosine kinase genes identified in the human genome, 58 encode receptor tyrosine kinase proteins. [1]

Other names in common use include beta-tyrosinase, and L-tyrosine phenol-lyase (deaminating). This enzyme participates in tyrosine metabolism and nitrogen metabolism . It employs one cofactor , pyridoxal phosphate .
There are two classes of pigments: black and brown insoluble eumelanins, which are derived from aerobic oxidation of tyrosine in the presence of tyrosinase, and the alkali-soluble phaeomelanins which range from a yellow to red brown color, arising from the deviation of the eumelanin pathway through the intervention of cysteine and/or glutathione.
Tyrosine is converted to dihydroxyphenylalanine (DOPA) via the enzyme tyrosinase. Then DOPA is polymerized into melanin. The copper-ion based enzyme-catalyzed oxidative transformation of catechol derivative dopa to light absorbing dopaquinone to indole-5,6-quinone is clearly seen following the polymerization to melanin, the color of the pigment ...
